"It has enabled us to entirely change the format of a vacuum cleaner, and to achieve Dyson's best ever cord-free machine performance.

"The Dyson Cyclone V10 TM vacuum is so light, so powerful, it can deep clean anywhere in your home, on any floor type.

"It is the reason I've stopped developing full-size vacuums."

Dyson has also announced new Dyson Pure Cool purifying fans which tell users how they're cleaning the room - the fans include a new LCD display which reports on pollutants in the home in real time, automatically displaying air quality levels.

Paul Dawson, vice president for Dyson health and beauty, said the £400 device would offer consumers new level of clean air in their homes.

"At Dyson we develop machines for real people and real homes, creating technology that works well in the test lab but more importantly doing what they're expected to do in a real-world setting," he said.

"To clean the air at home, a purifier needs more than a filter.

"It needs to automatically sense pollution, capture gases and ultrafine particles, and project clean air to every corner of the room.

"The Dyson Pure Cool purifying fan does all of this, making it the only purifier fan to clean a whole family room properly."
